So, Ilan, unswer you in detail.
First - I dont like Skype, its main. Write letters, phone, special chating program in real time - no problem. Before, I had too many indecent proposals to use Skype. For many guys its erotic entertainment, almost free. And everebody began: "i want serious relationship, bla-bla-bla", ending all proposal of virtsex.
Second, i live not along in flat. Its not my personal apartments. I have big different in time with Europe & other country. If i'm, communicate on skype, its usualy night & i'll be disturb my sleeping relatives. whisper not talk on Skype. And i think this situation actual for many girls on the site.

P.S. When 98% guys get free contacts in skype, e-mail, phone number, they relaxing. do not feel the competition . all his communication is reduced to a "hello, how are you, bye, see you later, can be".
